 QFieldCloud support `pg_service.conf` configurations too. You need to configure your PostgreSQL layers with "Offline editing" cloud action and store your service settings on QFieldCloud Project's Secrets page.
 
 Read more [how to configure PostgreSQL service](../reference/qfieldcloud/secrets.md) in the QFieldCloud documentation.
+
+## Creating a `pg_service.conf` File for PostgreSQL Connection in QGIS and Secrets
+
+Before beginning, ensure that your PostgreSQL database allows connections from QFieldCloud. Refer to [Technical specs](../reference/qfieldcloud/specs.md) for instructions.
+
+### Setup `pg_service.conf` File
+
+We first need to set up a configuration file. There are many options to organize this, [read more in the PostgreSQL documentation](https://www.postgresql.org/docs/current/libpq-pgservice.html) or follow the description below.
+
+1. **Create a Configuration File**:
+
+   - On Windows:
+     Create a file named `pg_service.conf` and store it in a convenient location.
+
+   - On Linux/MacOS/Unix:
+     Create a file named `.pg_service.conf` in your home folder (`~`).
+
+2. **Define Connection Parameters**:
+
+   Within the file, specify connection parameters for your PostgreSQL database using the following format:
+
+   ```plaintext
+   [SERVICE_NAME]
+   host=your_host_or_ip
+   port=your_port
+   dbname=your_database_name
+   user=your_username
+   password=your_password
+   ```
+
+   Replace placeholders (`your_host_or_ip`, `your_port`, `your_database_name`, `your_username`, `your_password`) with actual connection details and save the file.
+
+!![Parameters](../assets/images/service_config_file_001.png)
+
+### Additional Configuration Steps for Windows
+
+1. **Set Environment Variable**:
+   To ensure QGIS recognizes `pg_service.conf`, create an environment variable pointing to its location:
+
+   - Navigate to "This PC" or "My Computer" > Properties > Advanced System Settings > Environment Variables.
+   - Add a new variable:
+     - Variable name: `PGSERVICEFILE`
+     - Variable value: `C:\Users\<YourUsername>\AppData\Roaming\postgresql\pg_service.conf` (or your `pg_service.conf` file path).
+
+   Alternatively, you can set environment variables directly in QGIS via Settings > Options > System > Environment. Refer to [QGIS System Settings](https://docs.qgis.org/3.28/en/docs/user_manual/introduction/qgis_configuration.html#system-settings) for details.
+
+!![QGIS System Environment Variables](../assets/images/service_config_file_002.png)
+
+1. **Test the Connection in QGIS**: Open QGIS and set up a new PostgreSQL connection using the service name defined in `pg_service.conf` (e.g., `[MY_QGIS_DB]`) in the connection details. QGIS will read configuration from `pg_service.conf` automatically.
+
+   - Open QGIS.
+   - Go to "Layer" > "Add Layer" > "Add PostGIS Layers..."
+   - In "Create a New PostGIS Connection," select "Service" from the drop-down menu.
+   - Enter the service name from `pg_service.conf` (e.g., `[NINJA_DB]`) in the "Service" field.
+   - Click "OK" to connect to your PostgreSQL database using configurations from `pg_service.conf`.
+
+!![Test your connections](../assets/images/service_config_file_003.png,350px)
+
+1. **Add Parameter to QFieldCloud Secrets**: Navigate to the project's secrets page and copy the service directly from `.pg_service.conf` to the secret. Follow [Secrets](../reference/qfieldcloud/secrets.md) for guidance.
